Just been approached by someone here in Cardiff who runs Trip Database (www.tripdatabase.com/about), a widely used clinical search engine, used by health professionals across the globe (apparently they get 100 -110,000 visits per month). He's heard about our interest in social network analysis and mathematical modelling, and would like some help to analyse the Trip database.

This diagram is taken from a similar study: Clickstream Data Yields High-Resolution Maps of Science (http://bit.ly/OM9EW1) in PLOS ONE. It visualises the relationships between journals according to user clickstreams and describes a first-order Markov chain model to capture the structural features of its underlying clickstream model by comparing the latter to journal centrality rankings and an alternative model of journal relations derived from classification data. It uses PageRank methods too. In essence it produces a map of science research.

I thought I'd share as it looks pretty neat and some nice mathematical analysis behind it. Hoping we might get a MSc student working with them over the summer or a final year UG project next year.﻿

"Today, we're making it possible for you to go back in time and get a stunning historical perspective on the changes to the Earth’s surface over time. Working with the U.S. Geological Survey (USGS), NASA and TIME, we're releasing more than a quarter-century of images of Earth taken from space, compiled for the first time into an interactive time-lapse experience. We believe this is the most comprehensive picture of our changing planet ever made available to the public."

Can you explain your research using only the 1000 most commonly used English words?

Here's my attempt:

"To learn about early kinds of humans, I study small animals who are sort of like humans but with more hair. Groups of these small animals fight a lot - especially the women - and when they lose, they probably don't get to eat as good food. First, I want to know if groups that lose fights eat worse food than the groups that do not lose, and live in places where it is harder to get good food. Then I want to know if this makes life for the women in losing groups harder and keeps them from having as many babies as women in other groups.

I hope this tells us something about how fighting began in humans, and about why the small animal women spend time in groups. I also want to save these small animals, so knowing exactly what they eat and how their home makes their life easy or hard will help people keep them from disappearing."

The workshop is intended to broaden the scientific perspective of young researchers (primarily junior faculty, postdocs, and senior graduate students) in mathematical biology and to encourage interactions with other scientists.Workshop activities include plenary talks and poster sessions, as well as group discussions on issues relevant to mathematical biologists. Several abstracts will be chosen for short talks as well as to be presented as a poster. Limited funding is available on a competitive basis.

Voter suppression is a strategy to influence the outcome of an election by discouraging or preventing people from exercising their right to vote. It is distinguished from political campaigning in that...

AIDS is infamous for its rampant rise in Africa. Yet the biggest killer of Africa’s HIV-positive population — tuberculosis (TB) — has a much lower profile. Now researchers have unveiled a combination therapy that could cut the time taken to treat drug-resistant TB from two years to just four months.﻿
